<p>It seems to me that the <span style="font-family: Tahoma, Arial, Helvetica; font-size: 12px;">Envelope-to header is expected to contain the real recipient of the message as defined in the SMTP envelope from the original sender. If the host that first receives the messages puts some other address there you will have to talk to whoever manages that host to have them either put the proper address in that header or add one more header with it.</span></p><p>/Rolf </p>

<p>I've been a very happy user of Mercury for many years - so let me start by thanking all for a great product.  The issue I've just seen on 4.74, don't know if it predates it is as follows:</p><p>I bring my mail in from a host who forwards all incoming emails to my domain to a single account, which is then retrived and distributed by Mercury.   When a user emails in to one person with another at my domain in BCC, only the main TO recipient recieves email.  I saw this:  http://community.pmail.com/forums/post/11797.aspx, but checking that box caused all mail to be rejected.  With the below header, can someone point me in the right direction?  Thanks in advance.</p><p>Return-path: <externaluser@gmail.com> Envelope-to: mainaccount@organization.com Delivery-date: Thu, 21 Feb 2013 09:07:49 -0700 Received: from mainaccount by mysubdomain.bluehost.com with local-bsmtp (Exim 4.80)     (envelope-from <externaluser@gmail.com>)     id 1U8YgV-00070W-JT     for mainaccount@organization.com; Thu, 21 Feb 2013 09:07:48 -0700 X-Spam-Checker-Version: SpamAssassin 3.3.1 (2010-03-16) on mysubdomain.bluehost.com X-Spam-Level: * X-Spam-Status: No, score=1.5 required=4.0 tests=BAYES_50,DKIM_SIGNED,     DKIM_VALID,DKIM_VALID_AU,FREEMAIL_FROM,HTML_MESSAGE,RDNS_NONE,SPF_PASS     shortcircuit=no autolearn=no version=3.3.1 Received: from [74.125.XXX.YYY] (port=53950 helo=mail-ee0-f51.google.com)     by mysubdomain.bluehost.com with esmtps (TLSv1:RC4-SHA:128)     (Exim 4.80)     (envelope-from <externaluser@gmail.com>)     id 1U8YgT-0006xh-6X     for bccrecipient@organization.com; Thu, 21 Feb 2013 09:07:45 -0700 Received: by mail-ee0-f51.google.com with SMTP id d17so4732239eek.10         for <bccrecipeint@organization.com>; Thu, 21 Feb 2013 08:07:43 -0800 (PST) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed;         d=gmail.com; s=20120113;         h=x-received:mime-version:reply-to:from:date:message-id:subject:to          :content-type;         bh=IzT8eAqWZbb7g4PaKjHFzCyA38GlAChakwKJXzyHGeM=;         b=HnYWghZEU3LArXlqAQbli0W+jqM8Lbjn7Wy2FMiGbFI9lIil3Ml7vTJXIce6/NVGDv          4yRDypdSOrw8Y1Jxr/d++kr1GNpaY5/Dx9g02wPZFf5DJnAOLGm5p6W553ws2cNyIFce          7hH+/I0RKQU2ijkegN+ZUIDMGBXFXGk8EBWEmZ2EklgLD65V8jlt77K0vksGYOFQpUXZ          CJ80id4xV8zsZzri6je5Ydl75CFFxYjvc+DPDrG8tIqHasQ0MliWAWaoRBsQkFmuxmBn          N4ytxxIYVh570McrapSN+qpG9Ts+z1ODwNtf5A+nOguxguKaBBFQGkZi5+49lvE8YfW0          xnmQ== X-Received: by 10.14.211.65 with SMTP id v41mr81702748eeo.33.1361462863342;  Thu, 21 Feb 2013 08:07:43 -0800 (PST) MIME-Version: 1.0 Received: by 10.14.135.15 with HTTP; Thu, 21 Feb 2013 08:07:02 -0800 (PST) Reply-To: mainrecipient@orgnaization.com From: Someone <externaluser@gmail.com> Date: Thu, 21 Feb 2013 10:07:02 -0600 Message-ID: <CAMyjBgYhcXXRQhBmrT3FWBZC1xOw8_5u2haE_w_f=NmOXRZgAQ@mail.gmail.com> Subject: test To: Main Recipient <mainrecipient@organization.com> Content-Type: multipart/alternative; boundary=047d7b621e9c58613e04d63e46ee Bcc: bccrecipient@organziation.com X-Identified-User: {906:mysubdomain.bluehost.com:mainaccount:organization.com} {sentby:spamassassin for local delivery to identified user} </p>
